When can a metal roof be repainted?
All types of metal roofs are suitable for repainting, but it should be noted that newly installed metal roofs should not be changed for at least six months as they need time to resist.
However, before you paint a metal roof, you should also prepare it for the process ahead by removing mold, grime, and any loose paint that may have been left over from the original paint job.

After preparing the metal roof using a pressure washing treatment, you need to ensure that the correct processes are used to paint the roof. First of all, the correct type of paint must be selected.
Acrylic latex paint works well for bare metal roofs or for painting over old paint layers.

What kind of paint should i use for my roof?
Metal roofs have grown rapidly in popularity in recent years for both commercial and residential properties. Given the durability and longevity that metal roofs offer over other roofing materials, it is easy to see why so many homeowners are not opting for this material. While metal roofs don't require a lot of maintenance, if you want to paint your roof, it's important to understand a little about the proper type of paint to use.
Choose the type of paint
When choosing the type of paint to use on a metal roof, it is important to understand that not just any type of paint is appropriate. The roof of your home or commercial property withstands a significant amount of wear and tear, including ultraviolet radiation. As a result, it can become prone to fading and rusting over time. The right type of roof paint will ensure that your roof looks beautiful for a long time.
Choosing paint for a metal roof
Metal roofs often require paint that offers a high degree of elasticity. This is because metal roofs are prone to stretching and contracting. Traditional home paints are simply not appropriate for a metal roof because they are not elastic enough. As metal roof panels stretch and contract based on thermal expansion, traditional household paint will generally become brittle and crack over time. Peeling usually occurs shortly thereafter. Only paints specifically designed for metal roofs should be used. If the paint does not indicate that it is suitable for metal roofing directly on the label, it is best to omit it. In addition to making sure that the paint you choose is made especially for metal roofing, it is also important to ensure that the primer and top coat are also manufactured for use on metal roofs.
A water-based acrylic paint that is elastomeric is usually the best option to use on a metal roof. In addition to preventing cracking and peeling, this kind of paint is additionally fairly easy to clean should a problem arise. It also happens to be more environmentally friendly. Oil-based paints are also available and used frequently on historic projects, but they can be difficult to clean up in the event of an accident.
What else should I keep in mind?
In addition to considering the paint's level of resistance
to peeling and cracking, you should also consider how long the paint is
expected to last. A quality metal roof paint will typically last up to twelve
years, provided it is applied according to the manufacturer's instructions.
If you are uncomfortable painting the roof on your property or have questions about the correct type of paint to use, feel free to contact an experienced roofing contractor. The roof of your home or commercial building comprises a significant percentage of the investment you have in your property. Selecting the correct roof paint can ensure that your roof will not only look good in the future, but will hold for a long time as well.
